2) A little tykes toy car (mass = 7.85 kg) is left on a hill which is at an angle of,17 degrees. The toy car is a rest. The coefficient of kinetic friction between the toy and the ground is 0.33, while the coefficient of stati friction is 0.36. a) Draw the freed body diagram for the little tykes toy. b) Solve for the friction force.

    Where,

   $$\begin{gathered} N=normal force \\ {F}_f=friction force \\ m=mass of an object \\ \theta =Angle of inclined plane \end{gathered}$$

Toy is at rest hence, net force exerted on toy is zero.

Forces acting on toy in vertical direction are as follow:

$N=mg\cos \theta 1)$

Forces acting on toy in Horizontal direction are as follow:

$F_f=mg\sin \theta 2)$

We know that,

$$\begin{gathered} F_f={\mu }_{s}N 3) \\ where, \\ {\mu }_s=Coefficient of static friction \end{gathered}$$
